Vision defect determination via a dynamic eye-characteristic-based fixation point

A method being implemented by one or more processors executing computer program instructions that, when executed, perform the method, the method comprising:

• selecting, during a visual test presentation, a first interface location for a first stimulus based on the first interface location being farther from a fixation point than one or more other interface locations on a user interface of a wearable device of a user, the first interface location corresponding to a first visual field location of a test set, the one or more other interface locations corresponding to one or more other visual field locations of the test set;
• causing the first stimulus to be displayed at the first interface location on the user interface based on the selection of the first interface location;
• adjusting, during the visual test presentation, the fixation point for the visual test presentation based on eye characteristic information related to the user, the eye characteristic information indicating one or more characteristics related to one or more eyes of the user that occurred during the visual test presentation;
• removing the first visual field location from the test set;
• selecting, subsequent the removal of the first visual field location from the test set, a second interface location for a second stimulus based on the second interface location being farther from the adjusted fixation point than the one or more other interface locations;
• causing, during the visual test presentation, the second stimulus to be displayed at the second interface location on the user interface based on the selection of the second interface location;
• obtaining, during the visual test presentation, feedback information indicating feedback related to the first stimulus and feedback related to the second stimulus, the feedback related to the first or second stimulus indicating a response of the user or lack of response of the user to the first or second stimulus;
• and
• generating vision defect information associated with the user based on the feedback information.

One or more non-transitory computer-readable media comprising instructions that, when executed by one or more processors, cause operations comprising:

• selecting, during a visual test presentation, a first interface location for a first stimulus based on the first interface location being farther from a fixation point than one or more other interface locations on a user interface, the first interface location corresponding to a first visual field location of a test set, the one or more other interface locations corresponding to one or more other visual field locations of the test set;
• causing the first stimulus to be displayed at the first interface location on the user interface based on the selection of the first interface location;
• adjusting, during the visual test presentation, the fixation point for the visual test presentation based on eye characteristic information related to a user to which the visual test presentation is provided, the eye characteristic information indicating one or more characteristics related to one or more eyes of the user that occurred during the visual test presentation;
• removing the first visual field location from the test set;
• selecting, subsequent the removal of the first visual field location from the test set, a second interface location for a second stimulus based on the second interface location being farther from the adjusted fixation point than the one or more other interface locations;
• causing, during the visual test presentation, the second stimulus to be displayed at the second interface location on the user interface based on the selection of the second interface location;
• and
• generating vision defect information associated with the user based on feedback information indicating feedback related to the first stimulus and feedback related to the second stimulus, the feedback related to the first or second stimulus indicating a response of the user or lack of response of the user to the first or second stimulus.
